Usage

Add this to your Cargo.toml:

[dependencies]
pt-rtd = "0.1"

Examples

Conversion of temperature and resistance values:

use pt_rtd::{
    self as rtd,
    RTDType,
};

fn main() -> ! {
    let resistance: f32 = 100.0;
    let temperature: f32 = 0.0;

    // Convert resistance to temperature
    let result = rtd::calc_t(resistance, RTDType::PT100);
    let t = match result {
        Ok(temp) => temp,
        Err(e) => // handle error
    }

    // Convert temperature to resistance
    let result = rtd::calc_r(temperature, RTDType::PT100);
    let r = match result {
        Ok(res) => res,
        Err(e) => // handle error
    }
}

For relative mesurements, the library can also convert the ADC reading to a resistance value:

use pt_rtd::{
    self as rtd,
    ADCRes,
};

fn main() -> ! {
    let adc_value: u32 = 1000;
    let adc_resolution = ADCRes::B24;
    let ref_resistance = 5600;
    let pga_gain = 16;

    let result = rtd::conv_d_val_to_r(adc_value, ref_resistance, adc_resolution, pga_gain);
    let r = match result {
        Ok(res) => res,
        Err(e) => // handle error
    }
}
